Apple Logic Pro 9 - Manual (Page 248)

To freeze a track
1 Click the Freeze button in the track header.
Note: If the Freeze button is not visible, you can display it using the Track Header
Configuration dialog.
2 Choose the required Freeze Mode parameter in the Inspector’s Track Parameter box:
• Source Only: Freezes the track signal before it is fed into the first effect plug-in. Choosing
this mode turns the Freeze button blue.
Note: This Freeze Mode is useful when using CPU-demanding software instruments or
flex modes.
• Pre Fader: Freezes the track signal including all effect plug-ins. Choosing this mode
turns the Freeze button green.
Logic Pro will create freeze files after receiving the next Play command. This allows you
to activate the Freeze buttons of multiple tracks, and render their freeze files in one go.
Note: You can abort freeze processes by pressing Command-Period. In this scenario, the
portion of the frozen tracks that has already been rendered will remain in the freeze files,
and will be used for playback. Frozen tracks will remain silent beyond this point.
To change the freeze state of multiple tracks
Do one of the following:
µ
Click and hold the Freeze button of one track, then drag the pointer up or down.
The Freeze buttons of all swiped tracks switch to the same state.
